The discriminant is such a handy little tool, and this worksheet provides good practice in using it. The worksheet contains ten quadratic functions. For each function, learners are asked to provide three sections of information. First, they compute the value of the discriminant, then use that value to determine how many roots the function has and whether the roots are real or imaginary. The last part of the task is to use the value of the discriminant and the nature of the roots to determine the number of x-intercepts of the function's graph. This worksheet would be good to use for independent practice or group work during class, for homework, or for assessment.
